In this EA the Stop Loss is set automatically to the lowest possible value allowed by the broker, e.g. 2, 3, 5, or 10 pips. However, in some cases brokers have very low Stop Loss level, e.g. 1, 2 or 3 pips and it would be hit instantly, so you can increase the total stop loss using this Extra Stop Loss variable. In case of some ECN brokers the Stop Loss level is always ZERO, so it's best to use Extra Stop Loss value like 1, 2, or 5 etc. not ZERO
